Abstract

L'invention porte sur des moteurs à allumage par compression à double carburant et sur des procédés permettant l'allumage par compression de combustibles gazeux de type gaz naturel comprimé, hydrogène et ammoniaque, fonctionnant également avec des combustibles liquides, comprenant un carburant diesel pour des buts tels que le démarrage ou lorsque le combustible gazeux n'est pas disponible ou a été consommé et qu'une plage supérieure de temps de fonctionnement est nécessaire. L'allumage de combustible ayant une température d'auto-allumage élevée est assuré par recirculation de gaz d'échappement à haute température vers la charge d'admission avant la compression. On peut convertir les moteurs existants pour qu'ils fonctionnent comme des moteurs à double carburant par remplacement de la tête de moteur ou des têtes de moteur. L'invention porte sur différents modes de réalisation.
